they great just got my first several pairs a few days ago, If you sweat a lot, it helps, if you don't then fine. If you want so go swimming they double as a swim suit because they dry off quickly so you don't have to change into a swimsuit to go swimming you can just take your pants off and not look like a total tool wearing baggy jammers
The co's owners story about taking back his life is a great story and inspirational, he used to be a neo-nazi then decided to sell underwear. He literally worked as the water guy at gantanoma pay basically a buss boy, and then worked as the dog kennel guy raising woofy to bite where it hurts, but then realized he didn't actually hate the jedis, he just hated chafing, so He invented this underwear.
Check it out, personally I'm going to take a picture of me wearing them because I have a bulge and nice legs and put it on shethunderwears instagram. I've never had instagram but I'll see what its all about its all about trying new things. I've always wanted to be an underwear model but I've only done it has a hobby but I'm getting older so this could be my last shot.
